What Are The Similarities And Differences Of The Four California Regions? In this project, students are hired by the California Film Commission to persuade a Hollywood producer and team to film their movies in one of California's four regions. Students will learn about all four of California's regions and after becoming an expert on all of the regions, they will choose one region to research further. They'll create either a a region brochure or a 30 - 60 second commercial promoting their region. Included are a video, handouts, a reflection, Rank and Reason, and a rubric. This project is designed to have a structure compatible with implementing PBL in the classroom. NextLesson projects include certain key components that facilitate an authentic PBL experience.
